In current investigations the optoelectronic properties of perovskite structure-based (PSB) compounds are collected. The power conversion efficiency (PCE) dependency on device design and different transport layers are given in detail. The number of PSB compounds is taken into account as emerging materials for optoelectronic and spintronics applications. The electronic properties suggest that these PSB compounds have many properties starts from insulator to conductors and semiconductors. Furthermore, the best compounds for optoelectronic applications are suggested, which are organic-inorganic PSB (AMPbX3 (A=CH3NH3, X=Cl, Br, I) compounds, best for optoelectronic applications especially for solar cells.

In this study, phosphorus (PO43–-P) is removed from water samples using zinc oxide nanoparticles (ZnO NPs). These nanoparticles are produced easily, quickly, and sustainably using Onion extracts (Allium cepa) at average crystallite size 8.13 nm using Debye-Scherrer equation in hexagonal wurtzite phase. The bio-synthesis ZnO NPs characterization and investigation were conducted. With an initial concentration of 250 mg/L of P, the effects of the adsorbent dose, pH, contact time, and temperature were examined. At pH = 3 and T = 300 K, ZnO NPs, the optimum sorption capacity of 84 mg/g was achieved, which was superior to many other adsorbents. The isothermal study was found to be fit the Langmuir model at monolayer capacity 89.8 mg/g, and the kinetic study was found to follow the pseudo-second-order model. The adsorption process was verified to be endothermic and spontaneous by thermodynamic characteristics. As a result of their low cost as an adsorbent and their high metal absorption, ZnO NPs were found to be the most promising sorbent in this investigation and have the potential to be used as effective sorbents for the removal of P from aqueous solutions. The antimicrobial activity results showed that ZnO NPs concentration had a greater antibacterial activity than conventional Cefotaxime, which was utilised as a positive control, in the inhibitory zone. However, there was no inhibitory zone visible in the controlled wells that had been supplemented with onion extract and DMSO.

“…Semiconductor materials with wide-bandgap such as ZnO, SiC, GaN, and TiO2 have been used for producing Ultraviolet (UV) PDs and solar cells 2 – 10 . Among them, ZnO has attracted researchers' attention due to its unique features, including cheapness, high chemical stability, strong radiation hardness, high charge carrier mobility, and most importantly, the 3.37 eV wide-bandgap 3 , 6 , 11 – 14 . Ordinary PDs require an external power supply that increases system power consumption, costs, and system volume.…”

In this study, the effect of electrode shape difference on the height of the Schottky barrier and the electric field in flexible photodiodes (PDs) has been investigated. For this purpose, three different electrode designs were prepared on three flexible FR4 layers that were coated with Zinc Oxide (ZnO). The printing circuit board (PCB) method was used to create these copper electrodes. The asymmetry of the PD electrodes and the difference in the height of the Schottky barrier has led to the creation of self-powered PDs. The effect of the amount and shape of the distribution of internal electric fields generated in the PDs and its effect on the parameters of the PDs has been investigated with the help of simulations performed in COMSOL software. The photocurrent of the sample with circular and rectangular electrodes was equal to 470 µA in 15 V bias, which was twice as good as a sample with an interdigitated MSM structure. Also, this sample had the best response time among these three samples, which was equal to 440 ms.
